Antenna installations
First Claim
1. A sensor arrangement for an antenna installation which includes an antenna array located in an enclosure which is supplied with conditioned atmosphere supplied directly or indirectly from a dry air source, the sensor arrangement including a dew point sensor disposed in a flow path away from said enclosure, adapted to detect the dew point of atmosphere passing along said flow path, and an air flow sensor adapted to monitor flow along said flow path and to generate an alarm if said air flow falls below a predetermined threshold.

Abstract
An antenna installation comprises a plurality of antenna assemblies (10) mounted in respective enclosures (12). The enclosures are interconnected by flow connections (14) allowing passage of dry air supplied from a dry air panel (16). Having passed through all the enclosures, the dry air exhausts through a dry air return (18). The dew point of the air in the dry air return is detected by a dew point sensor (22). An air flow sensor (24) is disposed downstream of the dew point sensor and signals alarm if the air flow falls below a preset threshold.
